Why do you even use an admin account as your regular account? This is like running root for everything under Linux. I have trained some non-technical Windows users to always run their regular stuff as a non-admin user and they have never picked up a single virus in the past 10 years or so.
I've never picked up a single virus in 15+ years until last week. I did what I did and learned my lesson. If you want to pay for a t shirt that says stupid I'll wear it.
